Zoology is the scientific study of animals. This discipline can include animal anatomy, physiology, biochemistry, genetics, evolution, ecology, behaviour and conservation.
Certain neurons encode memories of events that occurred in specific physical locations known as place fields. Chickadees show patterns of neuronal activity that are specific to locations of hidden food but independent of place fields.
Both parents of oldfield mice care for offspring, whereas in deer mice, mothers usually care for pups. The discovery of a type of adrenal-gland cell that is present in oldfield mice but not in deer mice helps to explain the difference.
Some fox species leap up and pounce head first into snow to capture prey that they hear below the surface. An analysis of the forces involved reveals how the shape of the skull has evolved to minimize damage from this behaviour.
Birds vary in body mass by many orders of magnitude, but how this effects the evolution of their skeletal proportions is unclear. This study shows that small body size is associated with decreased evolutionary integration between wing bone sizes, facilitating increased evolutionary lability.
